中断加死循环程序就跑死了 优先级0比1高吧 而且中断响应的时间挺快的，最好想个别的方法验证

你好，问题解决了吗，我目前也遇到了模拟串口的问题，想请教一下

刘东晨晨晨

直接用寄存器 GPIOD -> DDR = 0X10; GPIOD -> CR1 = 0X10; GPIOD ->CR2 = 0X10;

radio2radio

加入判断条件，比如不是（0-9）就不是有效数字。 历遍所有元素，数一数有多少个是（0-9）范围的。

楼主你的问题解决了吗？我也遇到这个问题，我用的是ST-LINK烧录 但怎么都出不来，不知道是不是我少装了啥东西~

wjjontheway

想请教下楼主，MPU配置前和配置后有什么具体差异导致Hard Fault吗？

dbwu8280

同问同问。

奇迹

同一个中断函数，可能对应多个中断源，可能是其他中断源导致的

ckx775

估计是高优先级的任务影响

大象的耳朵

程序在U盘中打开，把U盘拔掉也会出现这种问题，找不到STM8的库

wyxy163@126.com

不用中断，还要检测外部事件，只能采用轮询模式啊，要么全部写进主函数，要么写一个独立的函数，主函数调用。。。。效果相比中断，差太多

真情才见真意

学习学习

这个好像不是吧，左对齐需要移一位，剩下15位，电流采样是注入组 应该是16位，左对齐移一位，数据是16位来存储，低四位为0---2020.1.8

skyflier

嗯，选择4M是为了省电，功耗有要求现在。 我再研究确认下，改下系统频率确认下，谢谢

我也一样，除了ST的stemwin LIB库,还去哪里找啊，他删减了，segger官网又不给,真操蛋
